›Powered by Gemini 2.0 — maintains persistent memory of what it has seen and heard
›Camera mode: point phone at anything — Astra reads receipts, explains diagrams, identifies objects live
›Cross-session memory: "Where did I leave my keys?" answered from earlier camera footage
›Acts across Google apps: drafts Gmail replies, creates Calendar events, searches Maps — all from voice
›Available on Pixel 9 Pro first; rolling to Android then iOS
›Requires Gemini Advanced (Google One AI Premium — $20/month)
›Astra is the product layer; Gemini 2.5 Pro is the underlying model
›Google positions Astra as an ongoing long-term platform — not a one-time feature
